Look and Feel of Vintage Vanity Fair Gown and Robe Set -Unbranded and Unsized-M?

Vintage gown and robe set. looks and feels like Vanity Fair. Can’t tell that tags were removed. Looks brand new. I am a large, and they fit everyone except the arm holes were a little tight, so I think it’s a medium. gown Measures 19” PTP and 38.5” long. The robe measures 19” PTP and 39.5” long. The set is soft and a beautiful baby blue or robin’s egg blue. Both pieces, one price! Thanks for looking and ask any questions!
